Abstract: A filter device for ambient air filtration has a blower housing with air inlet and air outlet. A device for generating an air flow is arranged in the blower housing and generates an air flow in operation from air inlet to air outlet. A flexible air conducting hose is provided with a first open end connected to the air outlet of the blower housing and with a second closed end. The flexible air conducting hose has openings arranged between first open end and second closed end. Filter elements are arranged in the openings, respectively. The filter elements separate a raw side inside the air conducting hose from a clean side downstream of the filter element. The air conducting hose is inflated in operation of the device by the air flow. The flexible air conducting hose has a reduced air permeability compared to the air permeability of the filter elements.

Abstract: A wheel for a motor vehicle comprises a rim having an outer radius and a wheel spider including a radially inner hub and a plurality of spokes extending from said hub towards said rim. At least one through-hole extends, with respect to the wheel axis, in a circumferential direction through at least one of said spokes. A radially outer edge of said through-hole or of an outermost of said through-holes is located at maximum at 75%, preferably at maximum at ?, of said outer radius of the rim measured at a wheel spider side of the rim.

Abstract: A protective cap for cylindrically mounted optical elements includes a retaining ring which is placed on a cylinder ring so as to be rotatable. The retaining ring covers the circumferential surface of the cylinder ring in a form-fitting manner. A latching mechanism having a latching element which engages in the latching mechanism in a force-fitting or form-fitting manner is present between the cylinder ring and retaining ring. The latching element is releaseable by an actuating element which is mounted on the retaining ring. A folding hinge for fastening and moving a protective cover from a covering position into a spatially fixed open position is present on the retaining ring.

Abstract: A vehicle wheel having a rim, or a rim of a vehicle wheel, is provided wherein the rim consists of a fiber-reinforced plastic material in the form of several layers of a fiber-reinforced semi-finished plastic product. The layers are shaped to form a finished component in a press while heat is supplied. The rim conventionally consists of a rim well, whose two sides are adjoined by a rim shoulder, which transitions into a rim flange. The rim well is formed by several layers of a base laminate, which extends to the rim flange, between which layers further layers are inserted in the area of the rim shoulder as well as of the rim flange. The further layers have an essentially tangential fiber alignment.

Abstract: The invention relates to a wheel (1), particularly a partially light-metal wheel and/or a light-metal wheel for motor vehicles, essentially comprising a rim (2) and a wheel spider (3), wherein the wheel spider (3) is made of a carbon-fiber-reinforced plastic. According to the invention, the wheel (1) has a clamping ring (4). The wheel spider (3) can be fastened to the rim (2) by means of the clamping ring (4).

Abstract: An optical assembly includes a connecting bridge to link up two autonomous optical units. The optical units are electronically connected to an analyzer. The connecting bridge is fitted each time with at least one coupling for each optical unit, said coupling making it possible, besides a mechanical coupling action, for the transmission of electronic signals and/or setting up an electric connection.

Abstract: The invention relates to a ring for a wheel rim of a wheel, particularly for motor vehicles, wherein the wheel rim has a rim inner well that merges into a rim inner flange, which, when the wheel is mounted, faces the motor vehicle, and a rim outer well which merges into a rim outer flange, so that the wheel rim has an uninterrupted contoured section on the axially inner side. The ring has a well lip, which extends up to the rim inner well or is designed to at least partially overlap the rim inner well. Ring has a flange lip, which faces away from the lip and is modeled on the shape of the radial inner surface of the rim inner flange. Ring provides or enables at least a partially double-walled in a hollow chamber region between the well lip and the flange lip.

Abstract: The invention proposes the damping of grain, for example, by creating a rotating layer (20) in a damping chamber (2) with the help of acceleration rotors (3). For this, the cross-section of the rotation chamber is designed to form an outer boundary around two or, preferably, three acceleration rotors (3, 3', 3"). In this way, the rotating layer is forced into an eccentric and spiralling motion within the damping chamber (2). Damping is carried out in a very gentle manner, so that there occurs hardly any abrasion and no grain damage. Additional advantages include a longer and controllable reaction period during damping, optimized preparation for milling and a shorter, controllable tempering period.

Abstract: A semolina cleaning apparatus allows basic operations as in the prior art with complete visual surveillance of operation, but with an outwardly closed product guidance. In this way, entry and exit of dust is completely prevented during normal operation as well as when removing samples. Accordingly, it is possible to operate an individual apparatus as well as an entire group of semolina cleaning apparatuses with circulating air. The air intake can be effected from above.

Abstract: An apparatus for separating grain material and for sorting out heavy inclusions from a product flow, particularly stones from gain material, in which the product flow is fed to an inclined layering table and guided so as to be substantially layered thereon. The layering table being acted upon by air flow and oscillated in such a way that the heavy inclusions lying directly thereon are conveyed up the table and guided away separately at the higher end. The feeding of the product flow is effected by way of a feed duct which opens to into the area of the higher end of the table and feeds the product into the separating zone of the product layers as a flow across the widest possible surface area, the separating zone being located in the area of the higher end of the table. The table has air guides for circulating. On an upper side, a closed hood is arranged and on an end side, a product feed portion is arranged. In the middle thereof, an outlet suction portion coupled to the closed hood is arranged.
